Description
The TCPP02-M18 is a MCU companion chip enabling cost-effective USB-C source
solution. It provides protections and functionalities to safely comply with the USB-C
specification.
On provider path, TCPP02-M18 drives external N-channel MOSFET to ensure
overcurrent protection on VBUS pin, as well as a discharge path. It features an
analog current sense and amplifier with an output accessible for a MCU ADC, thus
minimizing system cost.
The TCPP02-M18 features 24 V tolerant ESD protection as per IEC61000-4-2 level
4 on USB Type-C™ connector communication channel pins (CC). Also, it provides
overvoltage protection on CC1 and CC2 pins when these pins are subjected to short
circuit with the VBUS pin that may happen when removing the USB Type-C™ cable
from its receptacle.
TCPP02-M18 embeds I2C slave registers with two possible addresses, ideal for
dual-port chargers or multiple port applications.
